MACHINE FOR DOING OPENWORK-STITCHIN G.

T call whom it may concern:

Be it known that I, MATTHEW GOULD, a

subject of the King of Great Britain, residing-- Under my inventiontheneedles work together and they are simultaneously moved.

in the same direction, that is, to the one side or other so as to makethe double zig-zag stitch. The needles are not moved near to and thenaway from one another as in the well known spoke stitch machine.

In order that my said invention may be clearly understood I havehereunto appended explanatory drawings whereon:

, Figure 1' is a side elevation ofa spoke stitch machine of well knowntype with my improvements applied thereto. Fig. 2 is a plan of themachine. Fig. 3 is a view of the cam for operating the vibratingquadrant which vibrates the needles. Fig. 4 isa view of the needleblockswith their needles. Fig. 5 is a cross section taken on the line w, :20,Fig.

4' andshowing the arrangement of the needles and punches. the stitching.

On the drawings the same reference letters wherever repeated indicatethe same parts.

In carrying out my invention, say for pro- Fig. 6 is a diagram showingducing two rows of hemstitching on handkerchiefs, I arrange on theneedle bar a of 2.

Wheeler & Wilson spoke stitch machine, two vibrating blocks 1), c, theblock I) being provided with a needlee and the block 0 with a needle Theneedle bar has, fitted to it,

two punches g, 77,, the punch gbeing at the back of the needle 6 and thepunch h at thefront of'the needle f. The needle block b has a rod 41secured to it and this rod, at its upper end, is attached in the usualmanner Specification of Letters Patent.

[ to a link k which has, at its one end, a guide; slot lc working on thepin k and, at its other:

end, is connected adjustably to the usual vibrating quadrant Z which isfulcrumed at l The needle'block c has also a rod j secured to it which,at its upper end, is connected in the usual manner to a link m having,at its oneend, a guide slot m working on a pin m and, at its other end,is adjustably connected to at second vibrating quadrant n fulcrumed' atn;

Instead of the usual cam for operating'the vibrating quadrants, I use aspecial cam p.

which is shown at Fig. 3 to an enlarged; scale. 1 and 2 and depressionsat'S.

the cam are duplicates. The pinto offthes quadrant Z and the pin 0of'thequadrantn;

work in the groove of the cam.

It will be seen, es ecially from the enlarged view, Fig. 4, t at theneedle blocks are arranged .close together and so also are Of course thearranged.

The cam p is rotated in the usual manner by means of gearing from theshaft in the arm and as it rotates the so called quadrants- Z, n, arecaused to vibrate and they communicate their movements to the links is,m, the rods 'i, and the'needles e, When the pins 0, 0 are in theposition shown at Fig. 3, that is, at the points 1 of the cam, they movethe quadrants Z, 11, away from one another to; their fullest extent andbring the needles in line with the punches (see full lines, Fig. 4)

This cam is made with projectionsa-t.

Both ends-10f:-

and when the pins are opposite the pointsZ:

of the cam the same thing'oocursbut when the pins are at the points 3 ofthe cam. the

quadrants are brought near-to oneanother with the result that theneedles e, f, are moved to the one side, the needle f being moved awayfrom the punches while the needle e is moved from its position oppositethe unch g to a position 0 osite'the-punch h. In this manner the needlesaremoved; si-

multaneously either to the one side, as clearly indicatedin dotted linesat Fig; 4. oritozaposition in linewith the punches,asclearlyvinldicated; in full, lines at Fig. 4. movement of the needlesistotherightihan'd: side of Fig. 1 but of course it may be to the lefthand side according to the position of. the hem. The feed mechanism isthe same- The; lateral.

as that employed in the U. S. patent to Joseph Walker #634,970 grantedOctober 17, 1899.

I will now describe the formation of the stitch with reference to thediagram at Fig. 6. When the pins 0, 0 are in the position shown at Fig.3, thatis, opposite the parts 1, 1, of the cam, then the needles e, f,are in line with the punches g, h. The cloth is meanwhile being fedforward and. at the end of its forward movement the needles enter it atZ, Z, (Fig. 6). After i the needles rise again, the cloth movesbackwards and when the backward movement ceases the parts 2, 2, of thecam are acting on the pins 0, 0 and the needles enter the cloth at 2, 2,(Fig. 6). When the needles rise again, the cloth is again moved forward,and, at the same time, the cam moves round so as to bring the parts 3,3, opposite the pins, 0, 0 with the result that the needles are movedlaterally and enter the cloth at 3, 3, (Fig. 6). The usual gap in thefeed cam for operating the feed carrier now comes into action and allowsthe carrierto drop with the result that the cloth remains stationary foran interval. When the gap has been passed the cloth recommences itsforward movement and, at the same time, the parts 1, 1, of the cam 10come into action-on the pins 0, 0 with the result that the needles arebrought back to their original position opposite the punches and at thenext descent they enter the cloth l, 4; thereafter, the stitches arerepeated in the same manner as already explained.

It will be seen that there are two parallel lines of punch holes at 1,1, 2, 2, but there are no punch holes at 3 where the thread passesthrough the hem of the cloth.

The stitches at the back of the cloth are made in the same manner as onan ordinary Wheeler & Wilson spoke stitch machine.

It will be seen that the needles have two movements in the line of thepunches and thcpn a single lateral movement to the one s1 e..

The stitching produces a very pretty effect on handkerchiefs and suchlike.

By spoke stitch I mean a stitch such as shown for instance in the patentto Walker above referred to.

By arranging the unches so that one shall be disposed in t e rear of oneof the needles I am enabled to better produce the zig-zag stitch withminimum movement.

Having now fully described my invention what I claim and desire tosecure by Letters 2; A sewing machine having two needles movablyarranged on the needle bar side by side transversely of the direction offeed, two unches, one arranged in line with each needfe, vibrating meansfor the needles, and a cam for operating said vibrating means so as togive the needles two consecutive movements in order that they may enterthe cloth twice in line with their respective punches and then asimultaneous lateral movement in the same direction to enter the clothat one side of the punches.

3. A sewing machine having two needles arranged on the needle bar sideby side transversely of the direction of feed, a punch arranged in rearof one needle, a punch arranged in advance of the other needle and meansfor imparting to the needles a simultaneous lateral movement in the samedirection at every third descent of the needle bar.

4. A sewing machine having two needles arranged side by side. on theneedle bar, a punch arranged in rear of one needle, a punch arranged inadvance of the other needle and a cam for imparting to the needles asimultaneous lateral movement in the same direction at every thirddescent of the needle bar.

5. A sewing machine having two needles arranged side by side on theneedle bar, a punch arranged in advance of the one needle, a puncharranged in rear of the other needle, and means for causing the needles,during the formation of the stitch, to enter the cloth twice in linewith their respective punches and then once to move simultaneously inthe same direction at the one side of the punches, and means forimparting to the cloth one backward movement followed by two consecutiveforward movements.

6. In a sewing machine the combination with the needle bar, of needlesmovably secured thereto, rods connected with the needles, linksconnected to the rods, two quadrants, a cam for operating the quadrantsso as to impart to the needles a simultaneous lateral movement in thesame direction at every third descent of the needle bar and means forrotating the cam.

7. In a sewing machine the combination with the needle bar of needlesmovably secured thereto, punches, rods connected with the needles, linksconnected to the rods, two quadrants for actuating the links, a cam formoving the quadrants away from one another so as to bring the needles inline with the punches twice in each revolution and drawing them togetherso as to throw the needles to one side of the punches once in eachrevolution, and means for rotating the cam.

8. In a sewing machine the combination with the needle bar of twoneedles movably secured thereto, a punch arranged in rear of theneedles, a punch arranged in advance of the needles, rods connected withthe needles, links connected to the rods, two quadrants for actuatingthe links, a cam of oblong shape and having two correspondingprojections at each end and two corresponding depressions at the centerfor actuating the quadrants and means for operating the cam.

9. In a sewing machine of the character stated, the combination with theneedle bar and needles movably secured thereto, quadrants operativelyconnected with said needles, and means for moving said quadrants inopposite directions, the needles being at the same time moved in thesame direction.

10. .In a sewing machine of the character stated, the combination withthe needle bar and needles movably secured thereto, of quadrantsoperatively connected with said needles, and a cam operatively connectedwith both of said quadrants for moving said quadrants in oppositedirections, the needles being at the same time moved in the samedirection.

11. In a sewing machine of the character stated, the combination withthe needle bar and needles movably secured thereto, quadrantsoperatively connected with said needles, means operatively connectedwith both of said quadrants for moving said quadrants in oppositedirections, the needles being at the same time moved in the samedirection, a punch arranged in advance of one needle, and a puncharranged to the rear of the other needle.

In testimony whereof I afliX my signature in presence of two witnesses.
